Application 110d April 18, 1911. Serial No. 621,818.

To all whom it may concern:

Be it known that I, James F. HUNTER, a

. tachments for grain harvesters and consists in the novel construction and arrangement of its parts'as hereinafter shown and described.

The object of the invention is to provide an attachment of simple form which may be quickly and easily a plied to the frame of a harvester at the elivery edge of the grain deck thereof, the parts being so ar- I ran ed that the shocker will accumulate a num er of bundles and radually gravitate to lower the bundles to t e round. At the same time means is provi ed for turning the shock receptacle so that the shock will be positioned on end above the ound. After the shock has been position upon the ground means which normally holds hinged side panels of the shock receptacle -in closed ositions is operated whereby the said pane s are free to-swingl 0 1): cc

to permit the liberation of the s -At the same time the bundle which operates the 'same applied to the frame of a harvester.

Fig. 4 1s a rear elevation of the attachment applied to the frame of a harvester. Fi 5 is a side elevation of a portion of a stan ard used in the attachment. Fig. 6 is a transverse sectional view of said standard. Fig. 7 is a detail side elevation of a portion of theshock receptacle. Fig. 8 is a perspective view of a crahk shaft forming a part of the shocker attachment. Fig. 9 1s a perspective view of a trip mechanism forming a part of the attachment. Fig. 10 is a sectional view of shaft sections forming a part of the crank shaft shown in Fig. 8. Fi 11 is a perspective view of the rece tac e in tilted position in the first stage 0 the depositing of the shock u on the ground, the shock bein shown in p antom and the capping shea being also shown in phantom passing over the trip arm.

The attachment includes a receptacle embodying a frame 1 having side partitions 7 the top and rear being open. A shaft 2 projects from one side of the receptacle and 1s provided at a point intermediate its ends with a crank 3 and at one of its' ends a crank extremity 4. Spaced stub shafts 5 form sections of the shaft 2 and are held in proper relation with respect to each other by means of head plates 6 mounted upon the intermediate portion of the said shaft 2.

The sides of the receptacle are closed by partitions 7, as stated, and the bottom of the receptacle is normall closed by hinged panels 8. One end, or t e front of the receptacle, is normally closed by hinged panels 9 and a flap or chute. plate 10 is hin edly mounted at that end of the receptac e at which the panels 9 are located and normally overlaps the upper edge portions of the said panels 9. The panels 8 are normally held in closed positions by springs 11 which are mounted upon the end portions of the frame 1 and bear against the under sides of the panels 8 to hold them in closed position. The anels 9 are normally held in closed position by means of springs 12 which surround the end portions of the frame structure 1 and bear against the front sides of the said panels 9 and 10 to hold them in closed position. The panels 8 are provided with arms 13 which project outwardly beyond the hinged edge portions of the said panels and the panels 9 are rovided with arms 14 which project outwar 1y beyond the hinged edge portion of said panels 9. Rods 15 and 16 are pivotally connected together at their inner ends and the rods 15 at their lower ends are ivotally connected with the outer ends of t e arms 13. The rods 16 at their upper ends are pivotally connected with the frame 1 of the receptacle. Rods '17 are pivotally connected at their front ends with the arms 14 and at their rear ends with the intermediate portion of either the rods 15 or 16.

As shown in Fig. 7 the connection between the rods 16 and 17 is made. A shaft 18 is provided with bearings 19 which loosely receive the upper end portion of the frame 1 and the shaft 18 is provided with arms 20 which normally lie against the outer side of the panels 9. The shaft 18 is provided at one end with a crank extremity 21 and a trip the receptacle to lock the panels 8 and 9 in position. Springs 24 surround an end portion of the frame 1 and bear at one end.

against the under side of the apron 10 and have a tendency to hold the free edge portion of the said apron away from the inner surfaces of the panels 9. Standards 25 and 26 are mounted upon the frame of the harvester and the standard 25 is provided with an elongated slot 27 which receives one portion of the shaft 2 while the standard 26 is provided with an elongated slot 28 which receives another portion of the said shaft,

' -the slot 28 at its lower extremit being provided with a laterally dispose portion 29 across which extends a spring 30 against which the shaft sections 5 will hear when the shock receptacle is in its lowermost position the said spring serving as means to break the force of the shock-as the recepta-- cle moves to its lowermost position, and also serving as means to assist --in the return of the shock receptacle to its normal position after the shock has been deposited. The intermediate crank portion 3 of the shaft 2 is located between the standards 25 and 26. At theirupper ends the said standards 25 and 26 are connected together by means of a cross piece 31 having at one end an arm 32 and at its side an arm 33. A coil spring 34 is connected at its upper end wit-h the extremity of the arm 33 and at its lower end with the intermediate crank portion 3 of the shaft 2 to swing the receptacle when lowered. A coil spring 35 is connected at its upper .end with the arm 32 and at its lower end with the intermediate portion of the shaft 2 and is under tension with a tendency to hold the said shaft and its attached parts in elevated position thereby returning the receptacle to normal position after the shock has been deposited on theground. The tend- .ency of the spring 34 is to turn the shaft 2 upon its axis when the said shaft is lowered and. the shaft sections 5 enter the laterally disposed portion 29 of the slot 28 in the standard 26. A resilient armj36 is attached to the standard 25 and extendsforwardly beyond the receptacle of which the sides 7 and the panels 8 and 9 form com ponent parts. At its forward end A cable 38 is connected with the forward J portion of the .resilient arm 36 and at its rear end is connected with the crank 4 of a the shaft 2. A cable 39 is also connected with the forward. portion of the resilient arm 36 and isrtrained through an. eye 40 intermediatecrank 3 of the shaft 2. *The shaft 2 is journaled for rotation in a carriage' 41 which is provided at its ends with .carried by the said arm and the rear portion of the said cable 39 is connected with thewheels 42 which bear against the outer sides of the standards 25 and 26.

The operation of the shocker attachment is as follows. Presuming that the parts are in the positions as illustrated inFig. 1 of the drawings, the said positions being the nor mal positions of the parts. The bundles of grain as they fall from 'thedelivery end of the grain deck of the harvester enter thereceptacle between the sides 7 thereof and rest upon the hinged bottom panel 8. As the bundles accumulate in the receptacle the spring 35 will lengthen under the weight of the grain-and the shaft 2 together with the carriage 41 move downwardly along the standards 25 and 26. When the shaft sections 5 arrive at the laterally disposed portion 29 of the slot 28 in the standard 26, as-

sisted by the tension of thespring 34 which is connected with the intermediate crank portion 3, the said shaftand receptacle are turned upon the axisof the shaft whereby the bottom panels 8 of the receptacle are swung to vertical positions and the end panels 9 are swung to approximately horizontal positions. When this is done the bundles in the receptacle are turnedfrom horizontal to vertical position, but inasmuch as some of the bundles will rest upon the hinged flap 10 the panels 9 are, relieved of a great portion of the weight of the bundles.

By reason of the fact that the receptacle descends at the time it is turned the trip arm 22 will be carried into position just below the delivery edge of the grain deck of the harvester. Consequently when the next bundle is completed and it is ejected from the harvester it strikes the trip arm 22 and swings the same upon its hinged connection with the frame 1 outwardly beyond dead center. longitudinally which in turn will permit the shaft 18 to rotate and the arms 20 will be forced away from the surface which is now the lowermost surface of one of the hinged panels 9 by the weight of the bundles I of grain. Therefore the said panels are free to swing apart at their inner edge portions, and the apronlO will swing down under the This will permit the rod 23 to move weight of the grain held within the receptacle. Thus the bundles constituting t e shock are deposited upon .end at the surface of the ground and the final bundle which is 5 cast against the trip arm 22 is deposited on top of the shock and forms the cap bundle thereof. When the panels 9 swing to open posit-ions the arms 14 are swung about the hinged pivots of the said panels which in turn move the rods 17 longitudinally and the rods 15 and 16 are swung out of aline ment with each other into the position substantially as shown in Fig. 7 of the drawings. Inasmuch as the rod 16 is confined at one end by a pivotal connection with a portion of the frame 1 and at its lower end is pivotally connected with the rod 15 and in view of the fact that the said rod 15 is connected with the arm 13 the arm 13 will 20 be swung so that the bottom panels 8 will be swung open against the tension of the springs 11. It is to be understood that the panels 9 when swung to open positions are swung against the tension of the springs 12. Therefore as the panels open from each other there is sufficient space between the inner ends thereof to permit the said panels to sweep along the sides of the shock as the machine" and shocker pass beyond the same. At the time that the shaft 2 rotates and is a lowered the cables 38 and 39 connected with the crank portions of the said shaft have a tendency to pull the forward portion of the resilient arm 36 rearwardly so that thelate 37 is in close proximity to the side 0 the shock and vtherefore'the shock cann'ot tilt or fall in a forward direction but is held by the said plate 37 so that it is squarely deposited at the bases of the bundles upon the 40 surface of the ground.

After the bundles have been deposited upon the ground in the manner as indicated the tension of the springs 11 and 12 comes intoplay and the panels 8 and 9 are closed. At'the same time the said panels are relieved of weight and the tension of the spring 35 comes into play which elevates the shaft 2 in the slots 27 and 28 of the standard 26 and the rod 23 assumes substantial alinement with the tri arm 22 or swings past dead center where y the panels 9 and 8 are held locked in closed positions.

It will be noted that prior to the capping sheaf striking the trip arm 22, the rod 23 and the trip arm being in alinement or beyond dead center against the side of the receptacle will retain the panels 9 in position againstswinging outwardly, and necessarily the rod 17 connected to the rods 16 and 15 will prevent the panels 8 from swinging. Thus the respective panels 8 and 9 are retained in position until the capping sheaf strikes the trip arm 22 to swing the said trip arm and the rod 23 outwardly 55 beyond the dead center whereupon the panels are free to swing outwardly by virtue of the wei ht of the shock to deposit the shock'upon t e ground. Upon the shock passing out of the receptacle and the weight thereof being relieved from the panels 8 and 9, the said panels are again free to return to normal position by reason of the tension of the springs 11 and 12, and the' shaft 18 may be rotated to return the rod 23 and the tri 22 to normal position. It 7 will be noted that upon the panels 9 swinging outwardly to deposit the shock upon the ground, that the rods 17 are moved to break the joints between the rods 15 and 16 thereby permitting the panels 8 to open at the 30 same time withthe panels 9.
